LOOM-TEMPLE.

SPECIFICATION forming part of Letters Patent No. 415,172, dated November12, 1889.

Application filed July 13, 1887.

To all whmn it ntay concern.-

Be it known that I, CHARLES A. LITTLE- FIELD, a citizen of the UnitedStates, residing at Fall River, in the county of Bristol and State ofMassachusetts, have invented certain new and useful Improvements inLoom-Temples; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention has for its object to provide means whereby thetemple-bar or the bar carrying the temple-roll may be adjusted not onlyhorizontally, longitudinally, and vertically, but may also be turnedabout a line drawn centrally through the said bar from end to end inorder that when the said bar becomes worn by use it may be moved orturned on or with relation to the stand which connects it to thebreast-beam in such manner as to maintain the axis of the temple-rollsubstantially parallel to the raceway of the lay.

In this my invention the inner side of the breast-beam in practice hasattached to it, near each side of the loom, a slotted plate having aconcaved surface with which co-operates the conveXed face of the arm orshank of a stand made adjustable on the said plate. The stand referredto contains an adjustable guide made as a sleeve, which receives withinit the temple-bar, which at its outer end carries the usual temple-roll,cover, and trough. The temple-bar within the guide referred to issurrounded by a spring, and the guide and 'bar are connected by aslot-and-pin connection, whereby the bar is free to slide longitudinallyto a limited extent within the guide, but cannot move therein in anyother direction independently of the guide; but the guide may beadjusted within the stand in such manner as to maintain the stud or axisupon which the temple-roll turns parallel, or substantially, so to theraceway of the loom to which the temple is to be attached.

Figurel is a top or plan view of a sufficient part of the breastbeam ofa loom, near one end thereof, to show my improved temple mechanismattached thereto. Fig. 2 is an Serial No. 244,138. (No model.)

elevation of Fig. 1 looking at it in the (ll16C- tion of the arrowthereon. Fig. 3 is a righthand end elevation of Fig. 1, the said figureshowing, however, the end of the breast-beam, which is supposed to be ofmetal; and Fig. 4 is a section of Fig. l in the dotted line Similarletters of reference refer to like parts on the drawings.

The breast-beam A, which is and may be of any usual construction, hassecured to it at its inner side a supporting-plate O for each temple tobe used, the said supporting-plate having its side or face toward thelay (not shown) concaved, as at c, the said plate being slottedlongitudinally, as at c, and being attached to the breast-beam bysuitable bolts r r, the said bolts entering slots 0 in the said plate toenable it and the parts attached to it to be adjusted vertically on thebreastbeam. At its inner side the plate 0, along the edge of the slot0', has two lips 0 which bear against the breast-beam and complete achannel for the head g of the screw g.

The stand F is composed, essentially, of a hub having adownwardly-projecting arm or shank f, the side of which next the plate 0is convexed, as shown at Figs. 3 and 4, to fit the concaved face of thesaid plate, the said arm or shank being slotted at f to receive throughit the adj listing-screw g, the stern of which is free to slide in theslot 0' of the plate 0, and the head of the said screw being free tomove between the said plate and the inner side of the breast-beam, thesaid screw having applied to it a suitable nut 9*, which when turnedupon the screw holds the stand or arm in adjusted position, the saidstand being adjustable horizontally to acommodate the temple to thewidth of the cloth being woven, and also vertically, the verticaladjustment being in the are of a circle, whereby the rear part of thetemple may be raised or lowered for a considerable distance to meet thevarying conditions in relative height of the breast-beam and lay withoutmaterially changing the position of the temple-roll itself.

The temple-roll d, of usual construction, has as its axis or center ofmotion a stud or shaft 61*, supported in usual manner within a cap orcover (1 and a trough d", forming part of the said temple, an extensionof the trough having secured to it in usual manner a heel-piece Z, whichis struck by the lay to move the temple back with it.

The stud 61* and temple-roll d are carried by the temple-bar D, which,reduced in diameter for part of its length, is inserted in a cylindricalguide N, made as a sleeve fitted into the hub of the stand 1*, the guidebeing held in adjusted position in the said stand by means of suitableadjusting-screws f whereby when the screws are loosened the guide orsleeve may be turned or partially rotated within the stand to enable theaxis of the roll cl to be brought into position parallel, orsubstantially so, with the level of the raceway of the lay, and theguide to be adjusted horizontally in the stand F.

The bar D, within the guide or sleeve N, is surrounded by a spiral orother suitable spring e, and is also slotted, as at d, to receive a pinor projection 12, the said slot and pin permitting the bar D to slidelongitudinally for a limited distance within the guide N, but preventingit from turning around in the said guide.

Prior to my invention the carrier-bars inloom-temples have usuallybeenmade square to enter a square or loop-like piece of metal forming partof a stand by which to operatively connect the temple to the loom; butin practice the said sliding carrier-bars soon become worn at theircorners, and, not being held securely, they twist or turn in suchdirection as to throw the axis of the templeroll so far out ofparallelism with relation to the level of the raceway of the loom as tocause the temple to injuriously strain the cloth and produce bad work.By interposing a cylindrical guide or sleeve between the bar and stand Iam enabled to adjust the position of the guide or sleeve byslightly'rotating it, and thus compensate for all wear of the temple-bardue to its frequent reciprocations, this adjustment being one of thechief features of this my invention.

Prior to my invention I am not aware that such adjustment has ever beenprovided for in a temple, and therefore I do not desire to limit myinvention to the exact construction of the guide or sleeve or to theprecise devices shown by which the said guide or sleeve may be adjustedin the stand. By entirely inclosing the spring 6 within the guide orsleeve N all danger of soiling the fabric by oil applied to thetemple-bar is obviated.

I claim- 1. The stand having a cylindrical opening, means to support thestand, the cylindrical guide supported in said stand, the templebaradapted to slide in the said guide, and the operating-spring e, combinedwith means to hold the said guide in adjusted position 011 the saidstand, substantially as described.

2. The temple-bar, the temple-roll carried by it, the spring, and theguide or sleeve to receive the temple-bar, combined with the stand andwith means to permit the guide or sleeve to be turned in the said standto compensate for wear of the temple-bar, substantially as described.

3. The slotted temple-bar, the temple-roll carried thereby, the spring,and the guide or sleeve made circular externally, and a pin orprojection 12., combined with the stand, means to hold it, and withmeans to hold the said guide in the said stand, substantially asdescribed.

4E. The temple-bar, the temple-roller, the spring, the guide or sleeve,and the stand having the arm or shank convexed at one side, combinedwith the 'plate- 0, concaved at one side, and with a belt or screw toconnect the said arm and plate adjustably, substantially as described.

5. The plate 0, slotted longitudinally, as at c, the stand having theslotted armor shank, means to connect the arm and plate, the guide orsleeve cylindrical externally, and means to connect the stand and guideor sleeve, combined with the temple-bar, a roll d, the baractuatingspring (2-, and with a pin or projection to limit the extent of thelongitudinal movement of the temple-bar, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES A. LITTLE FIELD.
